Planning different level pose

Seriously planning for different level pose, for me is need to scratch my head. It had 5 different plans that need to get it done. From first time in yoga, beginner, intermediate, advance to themed class. By planning for these 5 lessons, I realise that is hard to plan for the first time and beginner as all the poses that need to do need to simplify it, need to stand on their side to think all the pose that they able to handle it. So I decide self-demo and find my friend try to do those first time in yoga pose and beginner pose. That way only more accurate to get the right pose for these learner.
